During Fedora 7 time frame the FESCo decision to not to rebuilds was
just for the release in part because it was late during the release
cycle and the decision whether we wanted to do rebuilds every cycle or
not going further was not supposed to be happening earlier this time.
Just a reminder again.

And I'm reminding you again that /if/ we do a rebuild, it will be coordinated
with the tools team if they have any features up coming that would take
advantage of a rebuild.

You are stating your view point which is well known by now but the last
time I asked for a decision on this, it was decided against by FESCo
just for Fedora 7 release. FESCo has so far not made a decision about
mass rebuilds in general afaik.
